Using extended EditText (or TextView) in the layout xml

i have the following code to add a custom font for my EditText as well as TextView

package com.usjp.xxx.yyyy;

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.EditText;

public class CustomEditTextWithFont extends EditText {
 public CustomEditTextWithFont(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init();
 }

 public CustomEditTextWithFont(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
 }

 public CustomEditTextWithFont(Context context) {
    super(context);
    init();
 }

 public void init() {
    Typeface tf = Typeface.createFromAsset((getContext().getAssets()),"CaviarDreams_Bold.ttf");
    setTypeface(tf ,1);

 }
}

and in my layout xml when i have

<com.usjp.xxx.yyyy.util.CustomEditTextWithFont
        xmlns:android="http://ift.tt/nIICcg"
        android:id="@+id/ET_password1"
        android:layout_width="300dp"
        android:layout_height="wrap_content"
        android:layout_above="@+id/BtnLogin"
        android:textColor="#666362"
        android:layout_alignLeft="@+id/ET_login"
        android:layout_marginBottom="31dp"
        android:background="@drawable/edit_text_design"
        android:ems="10"
        android:hint="@string/password"
        android:inputType="textPassword"/>

but then when running it says

Caused by: android.view.InflateException: Binary XML file line #25: Error inflating class com.usjp.xxx.yyyy.util.CustomEditTextWithFont

can someone please tell me what i'm doing wrong here? Thanks a lot in advance :)
